PIPE-CAI.

To all 'whom t may concern.'

Be it known that I, SILAS N. MALTERNER, a citizen of the United States, and a resident of Canton, in the county of St. Lawrence and State of New York, have invented a new and Improved Pipe-Cap, of which the following is a full, clear, and exact description.

This invention relates to smoking appliances, and more particularly to a cap for tobacco pipes.

In carrying out my invention it is an important object to provide a cheap, simple and inexpensive cap for the bowl of a smoking pipe having novel means for securing the same on the bowl, such means being adapted to engage interiorly with the bowl whereby the latter will not be defaced, while the cap serves to prevent the lighted tobacco from being blown out of the bowl, especially when traveling or automobiling or in windy weather, although the improved cap will prevent extinguishing of the lighted tobacco in stormy weather and will serve to permit the proper draft and burning of the tobacco.

I/Vith the above and other objects in view, the invention resides more particularly in the peculiar combinations and arrangements of parts which will be illustrated as a preferred embodiment in the accompanying drawings and described in the specification.

Reference is to be had to the accompanying drawings forming a part of this invention, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a perspective view of my improved cap applied to the bowl of a pipe, a fragmentary portion of the latter being shown; Fig. 2 is an enlarged longitudinal sectional view through the improved cap, the section being taken on the line 2-2 of Fig. 3; Fig. 8 is a cross sectional view taken on the line 3-3 of Fig. 2; and Fig. 4 is a bottom plan view of the improved cap.

In the illustrated embodiment of the invention, a fragmentary portion of a pipe is shown, the stem being indicated by the numeral 10 and the bowl by the numeral 11, while the cap applied thereto is indicated by the numeral 12. This cap is shown as formed of a circular plate or disk, preferably of thin sheet metal, and when in position as shown in Fig. 1 of the drawings uncovers the open top of the bowl.

i Specification of Letters Patent.

Application filed March 21, 1913.

Patented Apr. 21, 1914. Serial No. 755,842.

In order to removably secure the cap on the bowl said cap is provided with spaced pairs of slots 18 and 14, located at equal distances from a center line drawn through the center ofthe cap in their preferred form, and with the slots at the same sides located in longitudinal alinement. The cap is further provided with a somewhat wider but elongated slot 15 located-between the slots 14 and projecting beyond the ends of the same toward the adjacent peripheral edge of the cap.

Mounted diametrically of the top tace of the cap is a substantially inverted channelshaped guide 16, the same being ho-llowed out as shown, and having an open inner end and an outer end wall 17 which projects slightly above the top tace of the guide, and which is provided with a longitudinal passage 18 communicating with the atmosphere and with the hollowed o-ut portion of the guide. The opposed longitudinal edges of the guide are also formed with extensions which are slitted vertically to provide tongues 19 which are extended through the slots 13 and rebent outwardly to engage the bottom face of the cap and secure the guide to the cap. The other portions of the extensions are also disposed through the slots 13, and the extensions are severed or slit at right angles to produce angular engaging hooks or spurs 20, the engaging extremities of which are pointed and curved upwardly, as shown at 21. As clearly seen in Fig. 3 of the drawings, these hooks or spurs are directed outwardly in angular relation to the sides of the guide, and in this manner they are spaced apart in divergent relation, and besides serving as an additional attaching means for the guide also produce gripping means which are spaced suiiciently wide to insure proper gripping action with the interior face of the pipe bowl. The extensions above described are disposed relatively near the closed end of the guide, but at spaced-points with relation to said extensions the guide is provided with extensions 22 which are extended through the slots 14 and also rebent to contact with the bottom face of the cap plate as an additional anchoring or securing means for the guide.

The guide 16 above described constitutes the stationary part of a. clamping means forsecuring the cap or plate on the bowl. and the movable part 23, which is also ot' inverted channel shape and is of a size to freely move within the guide or stationary section. The movable section 23 is provided with an open inner end and a thickened outer end wall 24e having a longitudinal passage 25 also communicating with the atmosphere and with the interior of the movable section. This end of the movable section is also provided with an upwardly extending portion which, in conjunction with the upwardly extending portion of the end wall 17, form finger engaging portions to permit the movable section to be shifted longitudinally with relation to the stationary section or guide against the action of an expansible coiled spring 2G inclosed by the sections and abutting the end walls thereof.

The end wall 24 is provided with a depending angular hook or spur 27 preferably. formed integrally therewith and with its engaging portion or bill 28 curved upwardly in the same manner as the engaging portions or bills of the hooks 20 but extending in an opposite direction. This hoo-lr 27 is movable through the longitudinal slot 15, and under the action of the coiled spring 26 the engaging hooks are held in spaced relation bymovement of thevshank portion of the hook 27 through the slot 15 and against the outer end wall of the latter. Thus, when the parts are constructed as above described it will appear that by .compressing the spring 26 by movement of the section 23 with respect to the stationary section, the engaging hook 27 will be shifted longitudinally and inwardly in the slot 15 so that the hooks may be inserted within the bowl of the pipe, whereby upon freeing the movable section the hooks will be caused to bite into the interior face'of the bowl to securely attach the cap or plate on the latter. Thus, it will be .seen that the cap will not only be held from displacement, but by being constructed of a closure plate and held in position by two clamping members, only one of which is movable, the structure of the device is Y considerably simplified and none of the workingparts are exposed to view to detract from the appearance and ornamentation of the pipe. The tobacco will be prevented from being blown out of the bowl and a cool and clear smoke will be furnished, since the passages in the end walls of the sections freely permit the entrance of air, which air must pass through the coils of the spring, which will well serve the office or purpose of a screen or cleanser for the air in passing through the slot 15.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A cap for tobacco pipes comprising a disk-.like plate having pairs of slots therethrough, a substantially channclshaped section having extensions disposed through the slots for securing the same thereto and having hooks to engage the interior surface of a pipe bowl, a movable section operable in the first-mentioned section and having a similar engaging member movable through the plate, and spring means between the sections adapted to hold the same normally distended one with respect to the other, said engaging members being extended in opposite directions and having tapered bills.

2. A cap of the class described, comprising a cover plate having a slot therethrough, an inverted channel-shaped guide section anchored to the plate and having integral cngaging hooks extending through the same, a movable section operating in the firstnamed section and having a similar hook movable in the slot and disposed on a line between the aforesaid hooks, said sections having end walls provided with passages, and ay coiled spring between said end walls for moving the last-named section in clamping position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
